Collective Wage Proof 2026

Collective-wage proof that holds up to a customs audit

On 1 January 2026 the generally binding collective wage in the German building-cleaning trade rises. Anyone who doesn't document working hours per site and tamper-proof has a problem in an audit by the customs financial control unit. LiteLog delivers the proof – automatically.

Collective Wage Proof 2026

You don't pass a customs audit with Excel.

The customs financial control unit audits the building-cleaning trade closely. It checks whether the generally binding collective wage was paid – and whether the documented hours match reality.

With paper timesheets and Excel that is hard to prove. Entries can be changed afterwards, the site reference is missing, and nobody can show that the person was really on site. In case of doubt, that counts against the company.

Solid collective-wage proof needs three things: hours per site, unchangeable after recording, and exportable at any time. That is exactly what LiteLog delivers.

Myths & reality

Does the collective-wage duty even apply to us?

The most common misconceptions around collective wage and recording duties – and what actually applies.

Myth

We're not bound by the collective agreement – this doesn't apply to us.

Reality

The collective wage in the building-cleaning trade is generally binding. It applies to every company in the trade, regardless of agreement membership. The documentation duty applies to all.

Generally binding sector minimum wage under the German Posted Workers Act.
Myth

Our paper timesheets are enough as proof.

Reality

Timesheets show a number, but not who was where and when. They can be changed afterwards. In an audit, a tamper-proof, site-linked record is far more solid.

Section 17 of the German Minimum Wage Act requires start, end and duration of daily working time.
Myth

Digital time tracking is only worth it for large companies.

Reality

A customs audit doesn't distinguish by company size – anyone who can't produce site-level proof risks back claims. LiteLog scales from a single site to several hundred locations, bills per site, and is ready within days.

Records must be kept for at least two years under Section 17 of the Minimum Wage Act.

What makes collective-wage proof audit-ready.

Site reference

Hours recorded per site

Every check-in and check-out is linked to a site. The record shows not only how long, but also where.

Entries cannot be changed afterwards

After recording, entries are fixed. Corrections are documented as a separate event – the chain of evidence stays complete.

On-site proof

Check-in only at the place of work

Via NFC tag or QR code at the site. The scan proves that the person was actually on site.

Wage groups
